Beach hunting ergonomics

All the metal detecting gear I use for beach and water hunting was chosen with ergonomics in mind.
I use lightweight metal detecting equipment whenever possible, but if I have to use heavier gear I make sure it is well balanced.
There is nothing worse than not being able to search during prime beach hunting times because you have a bad back or tennis elbow caused by using heavy or awkward metal detecting equipment.
I often see people using heavy or awkward metal detecting equipment at my favorite Spanish treasure hunting beaches, places you have to put serious hours in to get lucky at.
Lugging a heavy unbalanced metal detector around without a metal detecting harness will effect your search coil sweeping motion, leading to poor ground coverage and of course an aching back, shoulders or arms.
Earlier in the week I saw a guy struggling using a heavy metal detector with a search coil mounted at the rear of the search coil, the front of the search coil was tilted up as he struggled to hold and sweep the heavy metal detector.
If you must use a heavy metal detector make sure you use a metal detecting harness to help you maintain the search coil in a level position thru out the sweeping motion.
A straight shaft can also help distribute weight and balance a metal detector, assuming your metal detector can be mounted on a straight shaft.
I also see a lot of scoops with small handles, why bend down to scoop every time when it is better to use a long handled scoop saving time and energy during the target recovery process at the beach.
Sometimes your choice of search coil can be a problem, why use a large and often heavier search coil if it is throwing the balance of your metal detector off.
Using a large heavy search coil for an extended time at the beach will lead to aches and pains and eventually time off recuperating backs, shoulders or elbows.
Using and maintaining a good metal detecting technique is essential for a beach hunter trying to cover a lot of ground so ergonomics are important.
Lightweight or well balanced heavier metal detecting equipment help you cover ground effortlessly  and help prevent bad backs and other aches and pains that can keep you away from the beach.
The heaviest metal detectors and search coils are often advertised as the deepest metal detectors or search coils, but what good is target depth if you negate any advantage using poor metal detecting technique caused by struggling to use the heavier gear.
